Saving expressions?

I have the following matrix in my CAS view and would like to save it for later use. The matrix has variables that I pre-assigned with values. What is the best way to save expressions in terms of variables as shown?

I tried to save it as a list but the saved entry does NOT carry variable names, just values.

Other questions I have:

- Why is it not possible to have upper case variable names in CAS? ex.: "Z"
- Is it possible to define variables using my computer and transfer them to my calculator?



Thanks

Hi Dands.

To be able to do that you'll either have to purge the variables, or just use single quotes around the matrix.

This way: med:='[[...]]';

Also, you can define variables through the conn kit, even works with copy-paste from spreadsheets!

The single letter uppercase variables are reserved in the calculator, that's why you can't use them as anything other than real numbers.
